.MOLD FOR CONCRETE POSTS. Y

Application led July 2,

To @ZZ whom z'z may concern.'

Be it known that we, NELSON F. HOWARD and COLONEL L. HOWARD, citizens of the United States, residing in Fairfield Township, in the county of rlippecanoe and State of Indiana, have invented a new and useful Mold for Concrete Posts, of which the following is a specification, reference being had to the accompanying drawings, and to the letters and 'figures of reference marked thereon.

The invention relates tov a mold whereby concrete fence posts may be molded -in upright position, and it has reference more particularly to a sectional mold for monolithic concrete. corner posts that have fence wire tightening appliances thereon.

An object of the invention is to provide an improved post mold of such construction as to be adapted to be compactly hauled Vor carried from place to place in knock-down condition, and adapted also to be quickly set up for use where a post is required.

Another object is to provide an improved mold for monolithic concrete posts which shall be so constructed as to be adapted for molding either a right-hand or a left-handv post adjoining a roadway with fence Wire tightening appliances on the posts that shall not project and be obstructive at the side of a roadway.

A further object is to provide an improved post mold whereby the monolithic concrete post may be rapidly moulded with anchoring devices accurately set therein, which mold shall be so constructed as to permit of its being readily removed from the molded post and the anchoring devices. A still furtheriobject isto provide a sectional post mold which shall have few and simple parts and no small lparts liable to belcome separated and lost when the mold is Vnot in use and stowed away, which mold shall be Ofsuch construction as to be durable and economical in use.

With the above mentionedV and 'other objects in view the invention consists in a post mold having mold sections hinged together and foldable, the mold sections being novel andhaving novel parts incorporated therein; and,`the invention consists also further in the parts and combinations and arrange-- ments of parts as hereinafter particularly described and further defined in the accompanying claims.

Referring to drawings,-Figure 1 is a pering in the mold so as to be embedded inthe invasa@ post; Fig. i is a fragmentary horizontal'section of the post illustrating the arrangement of the power worm which is mounted in a boxing embedded in the post, the winding shaft being also illustrated inV connection therewith in one 0f the two positions in which it may be arranged relatively .to the post; Fig. 5 is a fragmentarysectional'detail of the winding shaft and its center pin; Fig. 6 is a side elevation of the improved post mold; Fig. 7 is an `elevation showing the inward bracing coinero-f the mold; Fig.

Y

Similar referencecharacters in the differ'- ent figures of the drawings indicate corresponding elements orffeatures of construction herein referred to in detail.

The type of .post that the improved Vmold is designed to produce comprises a concrete foundation l which is made in an excavation in the ground Vand has a corner portion 2 to support winding shaft.V Thel post comprises also a column 8 havingvertical front or face sidesaand 5 "andinclined'rear Vor brace sides 6 and 7. The corner portion 2 of the foundation has aV center pin 81flXed therein which is adjacent either to thersi'de 4 or the vside 5 of the column as may be desired and it guides a winding shaft -91 for tightening and securing wire fencing'to the post, the upper portion of the shaft being guided in a bearing or boxing 10 having a shank 1l vconnected toa base anchor 12 either as shown or in relatively inverted positions vas may be required to correspond with the determined position of the center pin 8, in deciding whether to produce either a righ-thand or a lett-hand post. The arrangement of the Vfencing 21 and 22 in con nection with the post will be readily understood.

lThe improved post mold comprises two front side form sections 23 and 24 and two rear side form sections 25 and 26. Each form section has a straight bottom or base portion 27 designed to stand upon the toundation 1, and each section has an edge 28 that is at right angles or vertical relatively to base portion, and an inclined edge 29 that extends at an acute angle from the base portion ot the section. The mold sections preferably are composed of wood which `may be coated with waterproof substance. The section 23 has a cleat 30 fixed to the outer side thereof on the broader portion of the section, and a shorter cleat 31 on a narrower portion of the section, the section preferably having also additional cleats thereon, all the cleats being horizontal or parallel to the base bottom 27 of the section. The section 24 is likewise provided on its outer side with cleats 30 and 31. rl`he mold section 25 is arranged with its right angular or vertical edge adjacent to the inclined edge of the section 23, the section 25 standing at an inclination. The section V25 is provided on its outer side with cleats 32 and 33 that are arranged so that one end thereofv shall be in connection with the cleat-s 30 and 31 respectively and which extend therefrom upwardly to the inclined edge 29 ot the section 25. The other rear mold section 26 is similarly provided with inclined cleats 32 and 33 that are arranged to be connected at one end with the cleats 30 and 31 respectively, and at their opposite ends with the cleats 32 and'33 respectively. Strap hinges 34 are secured to the cleats 30 and 31 and to the cleats 32 and 33 whereby the sections 23 and 25 are hinged together; and the sections 24 and 26 'are similarly hinged together by means of strap hinges 34 secured to the cleats 30 and 31 and also to the cleats 32 and 33 j, the section 26 standing inv-inclined position with its right angled edge adjacent to the inclined edge of the section 24 and its inclined edge adjacent to the inclined edge'olf sec-tion 25. Such arrangement ot hinges insures close corner connections ot theniold sections and permits the sections to be folded back each to the other tor cainpactly carrying the sections.

The vertical edges oi? the sect-ions 23 and 24 are detachably connected together, preterably by means of hinge hasps comprising strap `plates 35 secured to the cleats of one section and hasp plates 36 hinged to the strap plates and having slots 37 therein, the hasp plates being detachably secured to the cleats .ot the adjacent mold section, preferably by means oi screw shanlrs 38 inserted in the cleats and having head portions 39 that are received through the slots and turned against the hasp plates. The inclined edges of the sections 25 and 26 are detachably connected together by means of hinge hasps having strap plates 35 secured to the inclined cleats on one of the sections and hasp plates 36 detachably connected to the inclined cleats on the adjacent section in the manner above described. This arrangement ot the cleats permits the parts oi the hinge hasps to lie fla-t onthe cleats and the hinge pins ot the hasps to be in alinenient each with the other.

rlhe frontsides 23 and 24 are provided with guides whereby to set the mold accinfately with respect the lower portion of the section 23 preterably having a guide strip 40 secured thereto and the section 24 having a similar strip 41 secured thereto, the ends of the strips that are `adjacent t0 the vertical edges et the sections having notches 42 and 43 therein, one ot the notches receiving the center pin 8, depending on the position the winding shatt is to be arranged relatively to the vertical corner of the post, whether right-hand or left-hand. The upper portions ot' the term sections 23 and 24 have slots 44 and 45 thcrein'extending from the vertical edges of the sections respectively to receive the shank 11 ot theshaft bearing 10 to hold the base anchor12 in proper position when filling thel mold with concrete, the slots preferably being immediately above the upper cleats on the sections, and the sections preferably are provided with strengthening' cleats 46 and 47 respectively that are arranged above the slots. At suitable positions the sections 23 and 24 have holes 48 and 49 therein respectively to receive the screw bolts 19 and 20 respectively whereby to support the boxing 15 in proper posit-ion while lling the mold with concrete. Y i

In practical use the mold is set up upon to the center pin 8, Y

the foundation 1 after the foundation is i against the center pin 8 as above indicated,

the sections of the mold being connected tomoved, which is accomplished readily after first manipulating the hasps and their connections. It will be understood that the sections 23 and 2e can be readily withdrawn from the shank 1l and that the screw bolts 19 and 20 are to be re-moved to permit the mold sections to be withdrawn from the boxing 15. After the mold sections are removed the sections that are hinged together are folded back and the two pairs may be placed together and connected together by means of the hasps and devices 39 as indicated in F ig. 8, the general arrangement of the four sections being indicated in F ig. ll so that the mold may be conveniently handle and carried, or stowed away for future use.
